This water block directly cools the GPU, RAM as well as VRM (voltage regulation module) as water flows directly over these critical areas thus allowing the graphics card and it's VRM to remain stable under high overclocks. EK-FC780 GTX Classy water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps.

Base is made of nickel plated electrolytic copper while the top is made of quality acrylic glass material. The sealing is ensured by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure. Block is mounted with enclosed M3x4 DIN7985 screws.

EKWB recommends the purchase of aesthetic retention backplate (EK-FC780 GTX Classy Backplate - Black) which improves the looks of your graphics cards and also provide some passive cooling to the VRM section.

G1/4" threaded fittings can be used on both sides of the FC terminal. Flow orientation doesn't matter and is thus not prescribed.

Up to four EK-FC780 GTX Classy water blocks can be used on a single ATX form factor motherboard by using EK-FC Terminal (DUAL, TRIPLE or QUAD type) system or other means of interconnectivity. Please note that EK-FC Bridge & Link system is not compatible with this water block.

Fittings are NOT included and are optional below!

PLEASE NOTE: - Due to immense variety of fittings/barbs available on market and no prescribed standards, we guarantee compatibility only for connectors bought from our web site.

This water block worked correctly on my EVGA 780 Ti Classified version 03G-P4-2888-KR purchased in February, 2014. The EK instructions were not clear that after you lift off the Fan/Heat pipe assembly, that there is a full metal "front plate" that you must remove for the water block to seat properly. Using the included TIM and thermal pad material (plus a small amount of TIM on the memory and VRMs)the fit is precise. I saw a 30C drop in top temps from 75C on air to 45C on water. I highly recommend this product. I am using the XSPC D5 with two 280mm radiators with 140mm fans in a pull only (so I can clean the radiator of dust easily). Water block is on CPU, motherboard VRM, and one 780 Ti Classified. Great card, always stays at boost of 1163MHz!

Awesome looking
